Open-source Firebase alternative delivering instant GraphQL backend
Nhost provides a fully managed, open-source backend with PostgreSQL, instant GraphQL via Hasura, authentication, storage, and serverless functions, supporting any frontend framework and easy self‑hosting or cloud deployment.

Nhost is a developer‑focused backend platform that replaces Firebase with an open‑source stack. It combines PostgreSQL, Hasura‑generated GraphQL, built‑in authentication, file storage, and serverless functions, all accessible through a unified CLI.
The instant GraphQL API lets you query and subscribe to data without writing resolvers. Authentication and storage are provided out of the box via Hasura Auth and Storage modules. Serverless functions run on Node.js, supporting both JavaScript and TypeScript, and client SDKs are available for JavaScript/TypeScript and Dart/Flutter, making the service frontend‑agnostic.
You can start instantly on the hosted Nhost platform with a few clicks, or self‑host the entire stack using the provided Docker‑compose configuration for full control over data and infrastructure. The Nhost CLI streamlines local development, testing, and deployment, ensuring a smooth workflow from prototype to production.
When teams consider Nhost, these hosted platforms usually appear on the same shortlist.
